AORE-MILL.

SPECIFICATION forming part of Letters Patent No. 437,017, dated September 23, 1890. Applicationiiled May 22, 189.0. Serial No. 352,690. (No model.)

To all whom, t may concern:

Be it known that I, HORACE J. CLARK, a citizen of the United States, residing at Westfield, in the county of Chautauqua, State of New York, have invented certain new and useful Improvements in Ore-Mills, of which the following is a specificatiomreference being had therein to the accompanying drawings.

This invention has relation to machines for breaking stones, ore, and other substances.

Among the principal objects of the invention are to reduce the cost of manufacture, secure facility of transportation by dispensing with parts having excessive Weight, increase the capacity of this class of machines, and facilitate their erection and use at points distant from its manufacture.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure lis a side elevation with parts in section, showing the internal construction of a machine embodying my invention. Fig.2 is aplan. Fig. 3 is a side elevation illustrating a series of machines embodying myinventionand connected with a single motor, and Fig. 4 is a transverse verticalsection on the line of Fig. l.

Like letters refer to like parts inall the figures of the drawings.

A represents the base or foundation on which the working parts and their accessories are mounted. The base is provided with a recess A', in which are arranged the stamps, the dies, and the pulverizers or rockers, as well as other accessories when all are employed.

The simplicity of construction of the base A is an important feature of my invention, both as regards the facility with which it can be provided in mining sections and the natural adaptation exist-ing to the labor and stress-Which are put upon it when the ma` chine is in operation. In mining sections the case is provided by simply cutting down and squaring up the body of a tree and cross-cutting the same to form the recess A. It can even be made by bolting together a number of timbers Where trees of sufficient size to form the base in one piece are not to be found.

rlhe end Walls of the recess receive the direct and full force of the blow of the crushing hammer on the end of the grain of the Wood, and thereby resist most efficiently the Wear and deterioration of the machine in what are acknowledged to be the Weakest and most tried parts of existing forms of similar mechanisms. The base is also self-containing, as the motor for operating the moving parts is mounted thereon.

B represents the cylinder of a motor, which is adapted to be operated by steam, compressed air, or any other Well-known motive force-that is to say, instead of employing a steam-cylinder as the motor an electrical or other motor may be employed, the important condition being that whatever motor is employed it shall be mounted directly on the base.

B is the supply, and B2 the exhaust, of the motor shown in this instance. B3 is the valvechest thereof, the rod B4 (see Fig. 2) of which is provided with adjustable nuts B5, between which and encircling the rod is a tappet B6, which is rigidly mounted on or connected with the piston B7. The piston-rod B7 may be integral and extended along over the base, or

a coupling BS maybe employed to connect the piston-rod proper with the stamp-carrying rod C and any other construction. Bearings Cone at each end of the recess A-are provided and secured to the base in any suitable manner.

D represents the stamp or hammer provided With a shoeD. The stamp orhammer D is mounted direct-ly o n the rod C,andfmay be rigidly secured thereto, so that it may be reciprocated by the motor B and coact with the dies E. A preferable construction, however, is to mount the stamp so as to Vreciprocate on the rod C and to provide cushioning devices F, which in this instance consist of springs encircling the rod C and regulated in their tension by clamps F which 1nay`be moved toward and away from the stamp for that purpose. I deem it important at this point to state that a horizontal reciprocating stamp connected directly with the piston-rod of a motor and provided with a single stamp proper or working face or shoe D is a very eective means for the purpose in view. In

IOO

such construction I would therefore prcferably employ but one cushioning device F, and that at a side (preferably upper) of the hammer opposite its working-face of stamp proper. The purpose of the cushioning de vices is to neutralize in a measure the stress upon the machine. arising from a reciprocation of the heavy hammer, the approximate weight of which is five hundred pounds, it being the heaviest piece in the mill. The cushioning devices have another object, in that upon the first impact of a shoe upon the stone resting against the die the stone is broken, and in the act of breakin git the cushioning device is compressed, whereby power is stored therein and the breakingr blow is immediately followed by a crushing action on the part of the stamp. In practice the cushioning devices are set at such a high tension that a moderate reciprocation of the stamp by the motor does not bring the shoe into contact with the die, although this particular adjustment is not adhered to, it being mentioned to bring out more clearly the fact that there is power stored therein to do effective work, as above described.

There are secured to the stamp hoods G, which, in connection with the similar overlapping hoods G', projecting from the recess, serve the purpose et' retaining within the battery proper particles of stone, which might iiy from between the shoe and die in the act of crushing.

A casting or plate .lfI is arranged in the bottom of the recess, and castings I protect the walls of the recess and are adapted toreceive the studs E of the dies E, which are made square in cross-section, in order that unequal wear of the face may be compensated by turning the die and inserting it in a reversed position into the casting I.

Rubber or other cushions I may be placed between the castings I in the end walls et' the recess. Similar cushions may also be arranged between the die and die-seats.

The box or trough, Fig. 2, constitutes partitions extending longitudinally in the recess of the base or in the battery proper, which partitions separate the battery into three seetions, in the middle one of which the stamp operates to accomplish the crushing. The two outer compartments are formed by castings or plates K, suitably secured to the base at the sides. These preferably do not extend to the top of the base, as clearly shown in Fig. l.

In the partitions .I are openings J', Fig'. i, which communicate with troughs J2, the inclined walls of which are provided willi screens J 3 and screen-proteeting gratos J These troughs provide means for the introduction of material into the middle compartment for the purpose of crushing it and the egress from said compartments of the crushed material, which passes through the grates and screens into the outer compartments. Vat-er may also be introduced by the same means, or independent pipes may be provided, as

shown at L, Fig. 2. A hopper may be provided upon one or more troughs, as indicated by dotted lines L', Fig. 2.

Hthin the outer compartments K K pulverizers or rockers M are arranged when employed in connection with the stamp, and these pulverizers or rockers are pivotally connected with the stamp-rod and rest upon the bottom plate of the recess. The pulverizers may be made of a single casting and with plain workingfaces, as shown in Fig. 3; but it is preferable to construct said pulverizers in sections, as clearly shown in Figs. 1 and 4, and to connect said sections by suitable bolts passing through slots M in one section and sea-ted in the companion section. Right and left screwthreaded bolts M2 may be employed also to maintain the adjustment of the sections upon each other, whereby any wear of the working-tace may be compensated.

In Figs. l and 2 I have illustrated one means of preventing a longitudinal movement bodily of the pulverizers along the bottom plate ll. The means illustrated in this instance for said purpose comprise a rackbar M3, formed or fixed on the bottom plate Il, and teeth M'l on the peripheral edge of the pulverizer. The plates of the milhwhen the invention is embodied in a quartz-mill, are arranged on a table N, (see Fig. 1,) upon which and the plates thereon the crushed and pulverized material is conducted over the plates K and K of the battery.

A knocking-table O may be employed in connection with the plates to treat the concentrates iiowing from the plates. In this instance the table O is suspended at the side ot the base by links O', pivoted to the side and to the table, and is operated by any suitable mechanism-for example, a hammer O2, pivoted at O3 to the base and projecting into the path of the rod C, which has a pin O, which at each outward travel of the pistonrod is brought into contact with the hammer, so as to cause itto strike the knocking-plate. These parts may be adjusted in accordance with the skill and judgment of the constructer and user so as to deliver a blow of the required power.

rlhe purpose of the tappet B is to regulate the supply of steam in accordance with the work being performed by the stamp, and is in its nature and operation similar to wellknown adjustable cut-offs. It will be noticed that in ease a stone breaks easily the piston moves quickly forward, and the tappet moving with it quickly shuts oli*l the steam. On the contrary, it' the work is harder than the average the reciprocation of the stamp is retarded, and the cutting off of the steam is similarly retarded, so that the supply is extended any time in accordance with the work to be performed.

The facility with which the principal elements of this machine may be duplicated is illustrated clearly in Fie. 3 and. requires no IOO IIO

special description, as it is a mere duplication. It may be remarked, however, if desired, a motor canbe applied at each end of the series of mills; but as this would require synchronization of a motive agent, it is deemed p referable to increase the power of the motor, as required. v

It is apparent that other constructions of amal gamatin g tables and plates and of knocking-tables may be employed than those herein shown and described. It is understood that these parts are duplicated, there being a set upon'each side of the base, and that material is delivered from each of the outer compartments onto said tables; but it will readily be seen that such an inclination can be given to the bottom of the battery proper as to deliver the material at one side only, and, if desired, but one pnlverizer or rocker M may be employed, and that other pulverizers or rockers than those which are constructed to oscillate might receive motion from the hammer or from its reciprocating and adjacent parts.

It will be noticed that the stamp proper is connected with the reciprocating mechanism at one side of aline extending through longitudinally its working-face. (See Fig. l.) By this particular feature ofconstruction I adapt the stamp to be reciprocated horizontally without complicating the mechanism employed and without the -necessity of arranging the means of reciprocation within the battery, where it would be subjected to undue abrasion by the material being crushed.

The direct pivotal connection of the pulverizers or rockers with the stamp results in two important advantages. The one is that it utilizes the weight of the stamp at the working-face of the pulverizer, and the other is th at the weight of the pulverizers or rockers, act to neutralize any springing out of aworkingline on the part of the stamp, and these features of the mode of operation I consider of great value, and hence I do not wish to be understood as limiting my invention to the reciprocation of the stamp by means which are connected with it only at one side of its workin g-path.
